Description

Technical Field

[0001] This application relates to the technical field of speaker jigs, and specifically relates to a universal positioning tooling for internal magnet speakers. Background Art

[0002] In the prior art, especially during the production of internal magnet speakers, each glue injection station requires a positioning jig. Dozens of glues are needed to bond speaker parts. When producing speakers, a very large number of positioning jigs are required for the same product. Moreover, the inner diameter of the existing speaker positioning jig is a fixed value, so it can only fix one size model of speaker for precise glue injection. Different sizes of speakers require customized positioning jigs of corresponding sizes, and when changing product production, the corresponding positioning jigs need to be replaced, which will lead to an extended time for product transfer and line change, increasing the labor waiting cost. At the same time, due to the addition of a large number of positioning jigs, the design and R & D cost of the jigs, the cost of the jigs themselves, etc. are increased. Multiple different sizes of jigs need to be customized, resulting in an extended processing time cycle. Utility Model Content

[0026] The following will be described in detail through specific embodiments respectively.

[0027] Reference Figure 1 and Figure 2 , an embodiment of the present application provides a general positioning tooling for an internal - magnet loudspeaker.

[0028] As Figure 1 and Figure 2 shown, the tooling in the embodiment of the present application includes:

[0029] A turntable 01;

[0030] Two fixing clamps 02, which are relatively arranged on the turntable 01, can move relatively, and the opposite surfaces 021 of the two fixing clamps 02 are concave surfaces;

[0031] A lead screw 03, whose two ends are respectively connected to the two fixing clamps 02, and is used to drive the two fixing clamps 02 to approach or move away from each other by forward or reverse rotation;

[0032] The positioning member 04 is arranged on the turntable 01 and is used to limit the position of the lead screw 03, thereby limiting the two fixing clips 02 connected to the lead screw, so that the common center of the two fixing clips 02 always remains substantially coincident with the center of the turntable 01.

[0033] In some alternative embodiments, a positioning groove 05 for fixing the internal magnetic speaker is formed between the two fixing clips 02, and the positioning groove 05 is coaxial with the turntable 01.

[0034] In some alternative embodiments, the opposite surfaces 021 of the two fixing clips 02 are V-shaped surfaces. In this way, the positioning groove 05 formed by the two opposite V-shaped surfaces can achieve a clamping and positioning effect on internal magnetic speakers of various different sizes.

[0035] In some alternative embodiments, the opposite surfaces 021 of the two fixing clips 02 can also be arc-shaped surfaces or other forms of concave surfaces, which are not limited herein.

[0036] In some alternative embodiments, the universal positioning tooling for the internal magnetic speaker of the present application further includes:

[0037] Two guide rails 06 are arranged oppositely on the turntable 01;

[0038] The two fixing clips 02 are respectively installed on the two guide rails 06, and the moving stroke is realized in a smooth sliding manner through the guide rails 06.

[0039] In some alternative embodiments, two grooves 011 are formed oppositely on the turntable 01, and the two guide rails 06 are respectively installed in the two grooves 011. Optionally, the height of the guide rail 06 does not exceed the depth of the groove 011.

[0040] In some alternative embodiments, one of the fixing clips 02 is connected with a right-handed nut 07, and the other fixing clip 02 is connected with a left-handed nut 08. The right-handed nut 07 and the left-handed nut 08 are respectively sleeved on both ends of the lead screw 03. In this way, when the lead screw 03 rotates, the two fixing clips 02 move relatively. For example, they move closer to each other when rotating forward and move away from each other when rotating backward.

[0041] In some alternative embodiments, both ends of the lead screw 03 are respectively threaded segments 031 for connecting the two fixing clips 02; the middle of the lead screw 03 includes a cylindrical segment 032, and the diameter of the cylindrical segment 032 is larger than that of the threaded segment 031; the positioning member 04 is used to limit the movement of the cylindrical segment 032 in the length direction of the lead screw 03.

[0042] In some alternative embodiments, the positioning member 04 includes two protruding portions 041, which are respectively clamped at both ends of the cylindrical segment 032, and the cylindrical segment 032 is limited between the two protruding portions 041, thereby realizing the limitation of the lead screw 03.

[0043] In some alternative embodiments, the turntable 01 is disc-shaped and can be used to be fixed on a glue injection machine.

[0044] In some alternative embodiments, the general positioning tooling for the inner magnetic speaker of the present application further includes: a connecting column 09, which is arranged at the bottom of the turntable 01 and is used to connect the turntable 01 to the glue injection machine. Exemplarily, the connecting column 09 may be connected with a pulley and is connected to the motor of the glue injection machine through a belt. Driven by the motor, the whole tooling is driven to rotate.

[0045] In some alternative embodiments, the positioning member 04 can be fixed on the turntable 01 by screws, and the fixing clip 02 and the guide rail 06 can be connected by pins.

[0046] In some alternative embodiments, the distance between the two fixing clips 02 can be equivalent to the outer diameter of the U-shaped iron of the inner magnetic speaker to be clamped.

[0047] Above, the embodiments of the present application propose a general positioning tooling for an inner magnetic speaker.

[0048] The tooling of the present application can be used as a general tooling fixture for speaker glue injection positioning. Fix its turntable on the glue injection machine, put the speaker into the tooling, and it is clamped and fixed by the two fixing clips of the tooling. After the glue injection program of the glue injection machine is debugged, the motor of the glue injection machine drives the tooling through a pulley, so that the tooling rotates, driving the speaker in the tooling to rotate. The glue injection needle of the glue injection machine descends to the debugged glue injection position to discharge glue, and the trajectory is customized manually to achieve ideal glue injection. Speakers have types such as inner magnet and outer magnet. The present application is mainly a general positioning tooling for inner magnetic speaker glue injection, usually used on various speakers of different sizes. By adjusting the lead screw, the positioning slot can reduce or increase the stroke (the size for the speaker to be placed) to achieve the general purpose.

[0049] The main purpose of the tooling of the present application is to achieve the general effect for various speakers of different sizes; the present application breaks the conventional fixed-size positioning fixture method, solves the difficulty that the industry purpose cannot be generally positioned, and through the rotation of the lead screw, the positioning slot retracts / expands back and forth and magnifies to achieve the positioning effect for speakers of different sizes.

[0050] Secondly, the opposite surfaces of the positioning slot designed in the present application may not be completely V-shaped surfaces, but can be further optimized, for example, increasing some arc smoothness, so as to be able to bear a lot of force when clamping and improve its positioning effect.

[0051] Thirdly, the present application first adopts a slide rail type stroke effect on the fixing clip. Through the rotation of the lead screw, the slide rail can slide back and forth. Using the slide rail as the stroke, the purpose is also to improve the smoothness and silkiness during debugging when switching speakers of different sizes and facilitate the use of the user.

[0052] Again, compared with the prior art, the present application adopts a new type of slide rail and a fixed clamp with a V-shaped surface, so that the accuracy consistency of clamping the product during the production process will be better, the durability of the product is improved, and the operation convenience of the user is improved.

[0053] Finally, the present application can achieve the general effect of an internal magnetic speaker, thereby reducing the purpose of switching the tooling to debug the injection molding equipment back and forth when changing the product model, improving the utilization rate of the fixture, saving costs, and greatly improving the positioning accuracy without moving the tooling, making the accuracy consistency better during the injection molding process of the product.

[0054] The travel length of the present application has been considered at the beginning of the design. Under the action of the lead screw and the slide rail, the maximum distance between the two fixed clamps can be designed to reach or exceed 40 mm, while the general size of the current internal magnetic speaker is within 36 mm, which can perfectly achieve the general effect; while improving the accuracy and consistency of the product, it reduces the efficiency loss caused by changing the product model and the tooling, improves the stability of the quality, and reduces the cost of tooling development and tooling.

[0055] Above, the technical solutions of the present application have been described in detail through specific embodiments. In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0056] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Those of ordinary skill in the art can modify the technical solutions recorded in the above embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and protection scope of the technical solutions of each embodiment of the present application.
